Ground-water control in the Neyveli lignite field, South Arcot district, Madras State, India
P.H. Jones, V. Subramanyam
1961, Economic Geology (56) 273-298

Several lignite seams occur in a thick sequence of sand, gravel, and clay that dips seaward about 40 to 100 feet per mile. The principal seam of lignite mapped in the Neyveli area averages more than 50...

F. S. MacNeil, J. A. Wolfe, D. J. Miller, D.M. Hopkins
1961, American Association of Petroleum Geologists Bulletin (45) 1801-1809
Recent stratigraphic and paleontologic studies have resulted in substantial revision of the age assignments and inter-basin correlations of the Tertiary formations of Alaska as given in both an earlier compilation by P.

Earlier studies of these deposits have shown that the...
